char bad_alloc[81]

the name of the array for which an allocation/deallocation error occurred

ipc_ f_eval

the total number of evaluations of the objective function

ipc_ g_eval

the total number of evaluations of the gradient of the objective function

ipc_ h_eval

the total number of evaluations of the Hessian of the objective function

rpc_ obj

the value of the objective function at the best estimate of the solution determined by BGO_solve

rpc_ norm_pg

the norm of the projected gradient of the objective function at the best estimate of the solution determined by BGO_solve
